Is there a way to execute a JavaScript function on a webpage using Selenium automation?

Question

Is there a way to execute a JavaScript function on a webpage using Selenium automation?

Here's an element on a website:

<span class="log-out-ico" ng-click="logout()">

Instead of clicking it, I want to run the "logout()" script from selenium. Is that possible? If so, how can I do it?

This is what I attempted:

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
js.ExecuteScript("logout()");

But I encountered this error:

Javascript error: logout is not defined

javascript c#angularjs selenium

Example page:

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<body ng-app="myApp">

<div ng-controller="myCtrl">
  <p>Click the button to run a function:</p>
  <button ng-click="myFunc()">OK</button>
  <p>The button has been clicked {{count}} times.</p>
</div>

<script>
a=function(){
console.log("hiii")
}
angular.module('myApp', [])
  .controller('myCtrl', ['$scope', function($scope) {
    $scope.count = 0;
    $scope.myFunc = function() {
      $scope.count++;
    };
  }]);
</script>
</body>
</html>

You may notice that the `myFunc` is not located inside the script block but within the Angular controller. It cannot be called directly.

However, the function 'a' is a regular JavaScript function so it can be called directly.

Execute `a` and check the browser console for the output "hiiii."

There are methods to expose an Angular function outside of the Angular module, but it is not a simple process.
